1995 E300 Air Conditioning Oil Capacity?

[DieselCJ]

Hello,
Been a while since I had a diesel MB, but I got one a month or so ago!

1995 E300 OM606 sedan.

A/C does not work, previous owner had it diagnosed... leaking A/C compressor.

Tomorrow the new compressor is arriving, I am also replacing the dryer and expansion valve. Last night I flushed the condenser, evaporator, and lines out with A/C flush and compressed air.

My question is how much PAG46 does the compressor take? I see some are "pre-filled", but it looks like some folks dump out the fluid and add a measured amount.

Searching around the net I find numbers ranging from 4.7 ounces to 8 oz!!

Thanks,
John H
